“A big site with multiple aspects.

Only a short distance away from the Gorges de l’Ardeche, explore the wonders of nature and travel through time, in the hearth of one of France’s biggest sites with the label of the Ministry of the Environment since 2004.

Hidden in a forest of evergreen oaks, the cave unveils its mystery where as above ground the first Europeans left their footprint while passing through this area…

Come and contemplate, the cave will impress you thanks to its massive volumes and the beaty of its subterranean landscape where nice crystallisations and concretions twine together.

During your 1 hour visit, a passionate tour guide unveils the genius of Lady Nature who for over millions of years shaped this magical world. This tour will lead young and old into a universe where imagination has no limit: piles of plates, forests of giant palmtrees, drapes, …
On this guided tour, 121 meters deep, a light&sound show highlightens the grandour of the environment, an emotional wave and everlasting souvenir before returning effortlessly with the elevator.
